2 Claims. (Cl. 198-93) This invention relates to an auxiliary conveyorattachment, adapted to he mounted on a conventional elevator conveyor todeliver material there to.

It is a denite problem in the handling of gran" ular products such assmall grains and the like to feed said material to the conventionalelevator conveyor units. The grain is often sored in large bins, fromwhich a large portion inf-.ist be shoveled in order to completely ernptythe bin.

It is an object of my invention to provide an auxiliary conveyorattachment, adapted to be mounted for vertical and horizontal swingingmovement at the material receiving end of a conventional elevatorconveyor for delivery or" material from a relatively inaccessible remotepoint to the elevator conveyor unit.

It is another object to provide an auxiliary conveyor attachment adaptedto be connected to a conventional elevator conveyor and to extend asubstantial distance horizontally outwardly from the lower materialreceiving end of conveyor.

It is still another object to provide an auxiliary conveyor attachmentor extension for connection with an elevator conveyor and constructed inthe form of an auger adapted to be driven from a source of rotary powerto deliver material to the elevator conveyor, and having a removablehopper unit surrounding a portion oi said. auger to permit said auger tobe used as a drag-out conn veyor as well as to receive the ilow ormaterial through a restricted outlet into the hopper.

It is a further object to provide an auxiliary conveyor attachmentprovided with a removable 0 mounting connection for securing thedelivery end of the auxiliary conveyor' to discharge inaterial into theelevator conveyor and having an upright mounting pin as well as asubstantially horizontal mounting pin to permit swinging movement on. avertical as well as a horizontal axis.

These and other objects and advantages of my invention will more fullyappear from the rollowing description made in connection with thecompanying drawings wherein like r erence characters refer to the saineor similar parte throughout the Several views, and in which:

Fig. l is a top plan view oi my conveyor aitaohment, as horizontallymounted on corn/enn l tional elevator conveyor, and showing the outlineci the removable hopper in dotted lines and showing the attachment inhorizontally swung position in dotted lines.

Fig. 2 is a side elevational view of my attachment with the hopperassembled thereon, and showing said attachment in inclined relation.

Fig. 3 is a transverse sectional view substantially along the line iii-3of Fig. 2.

Fig. l is an exploded perspective view showing the connector mountingfor the auger extension; and

Fig. 5 is an exploded view showing the parts of the hopper as removedfrom the auger extension.

As illustrated in the accompanying drawings, I provide an extensionconveyor consist" g auger l fixed to a rotary shaft t whic is journalledin suitable bearings respectively mounted in end plates i! and lil. Asbest shown in Fig. 5, the forward portion of the auger l .is enclosed ina casing li and a pair of opposed hopper mounting members l2 and i3 arefixed at their forward ends to the rear portion of casing il and aremounted at their rear ends on the end plate it?.

A hopper designated as an entirety by the letter A is removably mountedon the mounting members l2 and I3. A bottom closure casing lil sliclablymounted on the flanges along the lower edge of each of the mountingmembers i2 and it to enclose the bottom oi the auger l. A pair of endclosure plates l5 and lil are respectively connected at the forward andrear ends of the hopper. The end plate i6 may be removably secured toend plate lil as by suitable screws and the forward end plate i5 merelyrests on the top of the casing il. A pair of side plates il interconnectthe two end plates l5 and it and hold the forward plate lli againstshifting movement. A divider and distributing member I8 having aninverted V-shaped cross-sectional contour is interposed between said endplates iii and i6, and is secured thereto by the brackets i9. it shouldbe noted that the upper `portion of the hopper can be easily removed asa unit by merely removing the several screws along the upper flanges ofmembers l2 and I3 and removing the retaining screws, if any,interconnecting end plates it and lil. The lower portion of cover lf3.is merely slid outwardly to remove the same from the lower flanges ofthe members i2 and i3. It should be noted that the end plates l5 andt-'e retain the lower cover section li in position, and preventlongitudinal shifting movement thereof by abuting the end portionsthereof.

-A conventional elevator conveyor designated by the letter B is bestshown in Figs. l and 2 and has a relatively small hopper 253 at thebottom thereof, from which the screw conveyor 2l carries the grainupwardly, A discharge outlet 2?! is formed on the forward end of thecasing l i surrounding the forward portion of auger 'i for the conveyorextension on the lower side thereof, and discharges the material carriedby the auger into the hopper 2t. A mounting connection for removablysecuring the discharge end oi the conveyor extension to a conventionalelevator conveyor is provided as best shown in Fig. Li. This connectorconsists in a strap or mounting plate 23 having an upstanding pivot pinxed thereto. The mounting plate 23 is adapted to be rig idly secured tothe elevator conveyor as by being rigidly anchored to the side walls ofthe hopper 2o at the upper portion thereof as by suitable screws andnuts. It will be seen that the pin 24 is not disposed at right angles to'the mounting plate of strap 23, but is inclined relative thereto atapproximately an angle of 20 degrees less than normal. Since the maximumangleof the elevator conveyor is approximately 30 degrees, the

2O degree angle is approximately an average slope,

and will position the pin 24 substantially vertically relative to theground level to provide a substantially vertical axis on which theextension may be swung. A pair of sleeves 25 and 2t are in the formshown rigidly interconnected and the axes thereof are disposed at rightangles, one to the other. The sleeve 25 is adapted to be received on theupstlanding pin 2li and a pin -27 is `provided to extend through thehorizontally disposed sleeve 2G. A mounting bracket, such as thesubstantially Usshaped yoke member 28 is provided and is rigidly securedto the forward end 9 of the extension conveyor, as by being weldedthereto. The two spaced parallel arms of the yoke 2S are connectedrespectively at opposite ends of sleeve 2t by the pin '27 and thisoonnection permits swinging movement on a substanti'ally horizontal axisofthe conveyor `'exto sion to permit optimum positioning thereof. In theform shown, pin 2'! `consists in 'a bolt with a head Na 'and a nut 2lb.Also, itgsh'oul'd be noted that there is no means, other than the weightof the conveyor extension, for retaining' the sleeve v223 on the pin2?., thus permitting easy 'removal of the auxiliary conveyor.

The shaft t is 'driven by a drive shaft '29 connected at vits upper endto the power source 'for driving the auger '21, 'and has a tele'scopingportion to permit the length to be varied, and permit separation of thetwo telescoping sections. Any

suitable means, such as the polygonal male and female 'telescopingportions 'can be provided for producing the driving connection from oneend of the shaft 2E to the other. A 'universal joint .to is interposedbetween shaft '29 andthe Vauger shaft o, and is disposed substantiallydirectly above the pin Zal to facilitate the Vswinging movement bothhorizontally and vertically of the 'conveyor extension. A 'seconduniversal joint 31 is interposed into the upper 'portion of shaft 29,and permits the forward end 'of the 'extension conveyor to be lifted 'toremove the sleeve '25 from pin 2d, and separate the two sections of theshaft 2i; to permit the extension conveyor to be bodily removed from theelevator conveyor B.

With my improved extension conveyor, it 'is a relatively easy matter todeliver granular products from remote and relatively inaccessiblelocations to a main elevator conveyor such 'as the conveyor B. If thegrain is Vto be discharged through a restricted outlet, the hopper A ismounted on the rear portion ofthe auxiliary oonveyor extension, and ispositioned below the restricted outlet to receive the grain dischargedtherethrough. 4This hopper is of materially greater size than the hopper20, 4and is adapted to be positioned in substantially horizontalposition with the free end thereof resting on the ground surface to keepthe spillage 'at an absolute minimum. The divider plate I8 of the hopperevenly distributes the grain to the auger 1. The hopper A may be easilyremoved from the conveyor extension and the bare conveyor illustrated inFigs. 1 and 5 can be used merely as a drag-out conveyor by merely beingpositioned within the bin and substantially buried in the grain therein.The extremely simple mountingof the right angle sleeves 25 and 26 ontheir respective pins 24 and 21 permits the extension to be swung intosubstantially any desired horizontal position 'within certain maximumlimits.

It will be seen that I have provided an eX- tremely simple, yet highlyefficient, connection .for interconnecting a conveyor extension and aconventional elevator conveyor, which permits substantially universalpositioning of the conveyor extension for optimum efficiency indelivering granular material to the elevator conveyorto facilitateloading thereof.

It should be noted that the ease of removal of the hopper A is animportant feature of my conveyor extension, and that by simply removingthe side panels I7 from the mounting members I2 `and I 3, the entireupper portion of the hopper can be bodily removed and the lower casingI4 easily slid off from the mounting members I2 'and I3. If the endplate vor panel IB is secured to end plate I0, then, of course, it willbe necessary to remove any connections between said plates In and I6.

It will of course be understood that various changes may be made in theform, details, arrangements, and -proportions of the parts withoutdepartingfrom the scope of my invention.

What I claim is:

'1. An auxiliary conveyor extension comprising material transferringmeans, a driving conneotion connected with said transferring means andhaving a universal joint interposed therein, and adapted for connectionto a source of rotary driving power, a mounting connection at thedischarge end of said material transferring means including a mountingstrap adapted for rigid attachment to a suitable mounting structure 'atthe delivery end of said material transferring means, an opstandingpivot pin fixed to said strap and disposed immediately below theintersecting axes of the universal joint of said driving connection, asleeve journalled on said upstanding pin and Apivotally mounted at thedelivery end of said transferring means for swinging movement on ahorizontal axis.

2. The structure set forth in claim 1 and said vertically disposedsleeve being vertically removable from said upstanding pivot pin, and asecond universal joint in said driving connection to facilitate removalof said sleeve from the pin.
